Diagnostic imaging for vertigo and dizziness has remarkedly advanced and has been used to diagnose the central origin.<BR>We investigated here, the quality of diagnostic imaging for vertigo and dizziness to improve the diagnostic accuracy using 67 patients.<BR>The examinations included brain CT, MRI, MRA, target CT, SPECT, vestibular function test and audiological tests.<BR>Of a total of 67 cases, the following conditions were identified: Menier's disease; 15 cases, vertebral basilar insufficiency (VBI); 16, benign paroxysmal positional vertigo (BPPV); 3, vestibular neuritis; 10, acoustic tumor (AT); 6, lateral medullary syndrome; 1, cerebellar infarction; 1, cerebellar degeneration; 1, and pontile glioma; 1, and others; 13.<BR>We found different advantages of diagnostic imaging compared to the vestibular function tests. For example, in 20% of cases of Menier' s disease, the distance between the posterior semicircular canal and the posterior proteus surface (P-P distance) on CT was significantly shorter in the affected side than that in the normal side. In 43% of VBI cases, multiple lacuna infarctions were found using MRI.<BR>It is important to choose the appropriate imaging technique to directly diagnose or differentiate between various diseases. We discused here, the importance and the merits of imaging for the diagnosis of vertigo and dizziness.
